Subject [jira] [Created] (MATH-1284) Vector is-not-a Point
Date Sat, 24 Oct 2015 12:36:27 GMT
Roman Werpachowski created MATH-1284:
----------------------------------------

             Summary: Vector is-not-a Point
                 Key: MATH-1284
                 URL: https://issues.apache.org/jira/browse/MATH-1284
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 3.5
            Reporter: Roman Werpachowski
            Priority: Minor


The class hierarchy for geometry claims that Vector is-a Point: https://commons.apache.org/proper/commons-math/apidocs/org/apache/commons/math3/geometry/Point.html

This is mathematically incorrect, see e.g. http://math.stackexchange.com/a/645827

Just because they share the same numerical representation, Point and Vector shouldn't be crammed
into a common class hierarchy.
